GAS COOKING APPARATUS.

SPECIFICATION forming part of Letters Patent N 0.

776,033, dated November 29, 190d.

Application filecl July 21,1904. Serial No. 217,520. (No model l To cal], whmn/ it ITI/(LZ/ concern:

Be it known that I, LoUIs SoHoNn, a subject of the Emperor of Germany, residing at and whose post-oflice address is 25 Askanischerplatz, Dessau, Germany, have invented certain new and useful Improvements in Gas Cooking Apparatus; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a gas cooking apparatus; and its object is to providea burner, hot plate, and adjoining grid of such construction that perfectly uniform heating is insured in all parts.

in the drawings, Figure 1 is a longitudinal section; Fig, 2, a plan of the gas cooking apparatus, and Fig. 3 a partial section of the grid. 7

In gas cooking apparatus furnished with grids the burner is arranged in the middle of the hot plate, and the grid is thus at a considerable distance from the burner. In ordcr, therefore, to insure uniform heating of the whole surface, including plate and grid, it is necessary that the burner, as well as the hot plate and the grid, should be constructed in such a manner that the heating-gases are uniformly distributed.

T he improved gas-burner is adapted to meet these conditions, the upper edge of the flared mouth of the mixing-tube a being inclined downward in the direction of the grid (Z, Fig. 1, while the spreader g, which is furnished with an indented depending flange g, is held in a horizontal position by means of a pin a, looselyinserted ina boss it on the mixing-pipe (1/, so that the burner-openings between the teeth of the overlapping edge or flange g and the edge of the tube-opening to gradually increase in size in the direction of the grid. For the purpose of more easily adjusting the l )u1'ner-openings a screw it is inserted from be low in the boss it and serves as a support for the depending pin or shank t' on the flamespreader. By turning the screw [la the spreader g is raised or lowered and the burner made correspondingly larger or smaller.

The h eating-gases escaping from the burner a g naturally have the tendency to pass by the shortest way to the outletopenings m, (to the right in Fig. l.) Ribs o are therefore arranged radially to the head of the burner for the purpose of distributing the heat as uniformly as possible below the hot plate ruby means of which a suitable portion of the heating-gases is conveyed to both sides of the hot plate a and grid (1. In order also to'insure uniform heating of the grid (Z, the various bars (1 are constructed so that between each two spaces rin the grid a passage .9 is formed, which is completely covered in at the top, but entirely open at the bottom and at the end which is toward the burner. This construction of the grid would in itself not suilice for insuring the uniform heating of the bars, as here also the heatinggases have the tendency to reach the outlet m and spaces '1' by the shortest way, for which reason the spaces or slots r of the grid are partially closed, and, in fact, so that the spaces 9, which are shortest in the middle of the grid, become gradually longer toward the sides, Fig. 2, and. the drawing of the heating-gases to both sides of the grid correspondingly facilitated,whereby the uniform distribution of the heatinggases is promoted.

\Vhat claim, and ters Patent, is-

1. A gas cooking apparatus comprising a hot plate, a grid forming a continuation of the hot plate, a burner-tube opening below the hot plate and provided with a mouth or burner proper having an inclined upper edge, and a horizontal flame-spreader arranged to cooperate with the inclined burner-mouth to direct the greater portion of the flame toward the desire to secure by Let grid.

2. A gas cooking apparatus comprising a hot plate, a grid forming a continuation of the hot plate, a burner-tube opening below the hot plate and provided with a mouth or burner proper having an inclined upper edge, a horizontal flame-spreader arranged to cooperate with the inclined burner-mouth to direct the greater portion of the flame toward the grid, and means for adjusting the flan'ie-spremler relatively to the inclined mouth of the burner.

3. A. gas cookingapparatus comprising a hot plate, a grid forming a continuation of the hot plate, a burner-tube opening below the hot plate and provided with a mouth or burner proper having an inclined upper edge, an in-,

and adapted to uniformly distribute the heat- I ing-gases, a grid forming a continuation of the hot plate, a burner-tube opening below the hot plate and provided with a mouth or burner proper having an inclined upper edge, and a horizontal flame-spreader arranged to cooperate with the inclined burner-mouth to direct the greater portion of the flame toward the grid.

5. A gas cooking apparatus comprising a hot plate, a grid forming a continuation of the hot plate, and consisting of hollow bars arranged to form passages for the hot gases, a burnertube opening below the hot plate and provided with a mouth or burner proper having an inclined upper edge, and a horizontal flamespreader arranged to cooperate with the inclined burner-mouth to direct the greater por-- tion of the flame toward the grid.

6. A gas cooking apparatus comprising a hot plate, a grid forming a continuation of the hot plate, and consisting of hollow bars arranged to form passages for the hot gases, and separated by spaces or slots which gradually increase in length from the middle toward the sides, a burner-tube opening below the hot plate and provided with a mouth or burner proper having an inclined upper edge, and a horizontal flame-spreader arranged to cooperate with the inclined burner-mouth to direct the greater portion of the flame toward the grid.

In testimony whereof I have aflixed my signature in presence or two witnesses.
